Legumes and tall herbs had more new carbon in their shoots
In chambers with grassland blocks, species number showed no marked differences. Carbon went along with leaf nitrogen and height.
The study, in plain language
Carbon taken up by a plant can be distributed in different ways. The team moved blocks of soil and vegetation from a grassland into controlled chambers and tracked new carbon to compare communities with different numbers of species and plant types.
Species number produced no marked differences in several measures of labeled carbon. Instead, how much new carbon reached the shoots went along with traits such as leaf nitrogen, gas exchange, and height. Legumes and tall herbs had higher values than grasses and small herbs.
The key idea
In this setup, plant types and traits were more closely linked to new carbon than species number.
Something to think about
When you look at a grassland, notice which kinds of plants are there, not only how many: in this setup, that detail better tracked carbon’s path.
The original study
Functional composition has stronger impact than species richness on carbon gain and allocation in experimental grasslands
